Before using this product, the user must read and understand this document.
For additional information regarding this product, refer to the user guide and technical specifications.
All examples and diagrams are intended to aid understanding, and do not guarantee operation.
Unitronics accepts no responsibility for actual use of this product based on these examples.
Please dispose of this product according to local and national standards and regulations.
Only qualified service personnel should open this device or carry out repairs.
Failure to comply with appropriate safety guidelines can cause severe injury or property damage.
Do not attempt to use this device with parameters that exceed permissible levels.
To avoid damaging the system, do not connect/disconnect the device when power is on.
Environmental Considerations
Do not install in areas with: excessive or conductive dust, corrosive or flammable gas,
moisture or rain, excessive heat, regular impact shocks or excessive vibration.
Ventilation: 10mm space required between the PLC+HMIs’ top/bottom edges & enclosure
walls.
Do not place in water or let water leak onto the unit.
Do not allow debris to fall inside the unit during installation.

the flat surface of a Type 1 enclosure.
Wiring
This equipment is designed to operate only in SELV/PELV/Class 2/Limited Power
environments.
All power supplies in the system must include double insulation. Power supply outputs
must be rated as SELV/PELV/Class 2/Limited Power.
Do not connect either the ‘Neutral or ‘Line’ signal of the 110/220VAC to device’s 0V pin.
Do not touch live wires.
All wiring activities should be performed while power is OFF.
Install an external circuit breaker. Guard against short-circuiting in external wiring.
Use appropriate circuit protection devices.
Unused pins should not be connected. Ignoring this directive may damage the device.
Double-check all wiring before turning on the power supply.
Caution
To avoid damaging the wire, use a maximum torque of 0.5 N·m (5 kgf·cm).
Do not use tin, solder, or any substance on stripped wire that might cause the wire
strand to break.
Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure
Use crimp terminals for wiring; use 3.31 mm ² –0.13 mm² wire (12-26 AWG):
1. Strip the wire to a length of 7±0.5mm (0.270–0.300“).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.
Wiring Guidelines
Use separate wiring ducts for each of the following groups:
oGroup 1: Low voltage I/O and supply lines, communication lines.
oGroup 2: High voltage Lines, Low voltage noisy lines like motor driver outputs.
Separate these groups by at least 10cm (4"). If this is not possible, cross the ducts at a 90˚angle.
For proper system operation, all 0V points in the system should be connected to the system 0V
supply rail.
Allow for voltage drop and noise interference with input lines used over an extended distance.
Use wire that is properly sized for the load.
Earthing the product
To maximize system performance, avoid electromagnetic interference as follows:
Use a metal cabinet.
Connect the 0V terminal directly to the earth ground of the system.
Use the shortest, less than 1m (3.3 ft.) and thickest, 2.08mm² (14AWG) min, wires possible.
Inputs
This model comprises a total of 13 inputs in 4 groups.
1. I0 to I8 are digital inputs. They may be wired, in a group, as either npn or pnp.
2. I9 and I10 may be wired as either digital or analog inputs. These may be wired as either:
npn digital inputs
pnp digital inputs
analog (voltage) inputs
In addition, 1 input may be wired as a pnp input, while the other is wired as an analog input.
Note that if 1 input is wired as an npn input, the other may not be wired as an analog input.
3. AN1 is an analog (current) input that may be wired using 2, 3, or 4 wires.
4. Analog Input 0 can function as either thermocouple or PT100 input.

Digital Inputs
Note: The inputs are arranged in two groups. You can wire one group as npn and the other as pnp,
or wire both groups as npn, or as pnp. In either case, the npn/pnp pins must be connected.
